Science
Mechanism of Action
This oil operates through its high concentration of linoleic acid (LA) and gamma-linolenic acid (GLA), which are vital precursors for anti-inflammatory eicosanoids, crucial for healthy skin function. LA is integral to ceramide production within the stratum corneum, reinforcing the skin's protective barrier and preventing transepidermal water loss (TEWL) for improved softness and elasticity. GLA contributes potent anti-inflammatory effects by suppressing mediators such as IL-1β, IL-6, and TNF-α, while its metabolites also exhibit anti-inflammatory and anti-proliferative properties. Furthermore, it supports skin cell regeneration, provides antioxidant benefits, deeply moisturizes, and can assist in sebum regulation to mitigate breakouts.
